Biology I Exam UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
5 steps of scientific method - CORRECT ANSWER 1. Observation
2. Question
3. Hypothesis
4. Experiment
5. Conclusion
Observation - CORRECT ANSWER act of viewing the world around us
Question - CORRECT ANSWER made based off of an observation
Hypothesis - CORRECT ANSWER a tentative explanation for an observation
Controlled experiment - CORRECT ANSWER - test several groups
- introduce a single variable per treatment
- keep conditions as similar as possible from one group to the next
Conclusion - CORRECT ANSWER supports/refutes hypothesis
- more experimentation needed if refuted
Prediction - CORRECT ANSWER a guess of what might happen based on observation-- the
outcome you would observe if your hypothesis was supported
Theory - CORRECT ANSWER a sound explanation of the world supported through continued
observation and experiments over a long period of time
3 components of a controlled experiment - CORRECT ANSWER 1. Variable
2. Test group
, 3. Control group
Variable - CORRECT ANSWER feature of an experiment that is changed from one treatment to
the next
Test group - CORRECT ANSWER exposed to variable in an experiment
Control group - CORRECT ANSWER not exposed to the variable in an experiment
Importance of test group & control group - CORRECT ANSWER they allow researchers to
determine whether the variable in an experiment has an effect
Independent variable - CORRECT ANSWER manipulation performed on the test group
(ex. Hours of tutoring)
Which axis is the independent variable found on a graph? - CORRECT ANSWER x-axis
Dependent variable - CORRECT ANSWER effect that is being measured
(ex. Test score)
Which axis is the dependent variable found on a graph? - CORRECT ANSWER y-axis
Theory of evolution - CORRECT ANSWER set of hypotheses that provide a powerful
explanation for both biological observations & the diversity of life
Why do we learn that the theory of evolution is the single most important theory in all of biology? -
CORRECT ANSWER there's lots of evidence from asking/testing good scientific questions
(ex. Anatomy, fossil record, biogeography, molecular biology)
7 ways living organisms are different from non-living organisms - CORRECT ANSWER 1.
Organization - complex organization
